`Letters Patent-No, 111,430, dated January 31, 1 871.

IMPROVEMENT IN CUPS FOR KEROSENE-LAMPS.

vThe Schedulereferred to in these Letters Patent and making part of the same.

Be it known that I, NA'rHANlEn L. BRADLEY, of Meriden, in the county of 'New Haven and Strate of Connecticut, haveA invented a new Improvement in Cups lfor Kerosene-Lamps; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute -part of this specication, and represent in bracket, the bottom of the cup being slightly if any thicker than 'at any other part. y

As the oil drips over the outside of the fountain it necessarily concentrates in the center of the cup, and, the screw extendingthrough, the oil soon works its way around the thread and drips from the bracket. This difficulty has prevented the use of ,this class of burncrsforrst-class purposes, and whenever used it is found necessary to often wipe the bracket or wind some absorbent around the bracket to take the oil.

rlo overcome these diiculties is the object of my invention, which consists iu forming a socket on the under side of the cup, so that the bearing for the screw may be formedentirely outside the cup and thus give a solid bottom.

A isthe cup.

B, the socket.

C, the bracket-arm, upon which is formed a screw, d.

The socket is drilledand tapped to correspond to the screw d, and the socket is entirely belowthe cup, so that the bottom of the cup ,is not perforated; hence all liability for the oil which flows into the cup .to escape is avoided, and I make practical an important branch of manufacture which ha`s heretofore been hindered from 'the impractic'ability of its construction. I claim as my'invention- 4 In the manufacture of cups for kerosene-lamps the arrangement ot' the socket B upon the bottom of the cup, so as to form a hearing entirely below the bottom of the cup, substantially in the manner and for the purpose set forth.
